Care Instructions: The oral topper is removable for easy cleaning. Cleanup is a snap after the fun with Refresh Toy Cleaner and warm water. Do not submerge the PDX Elite Blowjob Power Pump in water. If desired, use a water-based lotion like Moist with this product. Operating Instructions: Power On – Press the top button to turn on. There are 2 modes of suction. IST starts in the first mode, continuous suction. Press the button again to switch to the second mode, intermittent suction. Pressing the top button will alternate between continuous suction and intermittent suction. Press and hold the top button for 3 seconds to turn OFF. Quick Release - Press and hold the bottom “R” button to release suction, or pulse the “R” button for extra stimulation. Alternate release method: Press down on surrounding skin to break suction seal. During intermittent suction, the “R” button will flash on and off as suction is automatically pulsed.
